Q7. If you were to move the north pole of a bar magnet into the front of your coil, what is the direction of the induced current when viewed from the front? To reach your conclusion, answer each of the following (see next page): Motion of the magnet as viewed from above. The arrows by the magnet indicate the direction in which the magnet moves, not necessarily the direction of B. a) Is the flux within the coil increasing, decreasing, or remaining constant? Explain in the space below. b) Viewing the coil “from the front", what is the direction of Bo within the coil? Done as an example to clarify perspective. "From the front" means looking into the coil.
